Figure 10-6 shows the logical network equivalent to the connections shown in Figure 10-5 above. A local
system with PCCU (1) can establish connections to each daisy-chained device on the same network (3).
Each device must have an IP address with the same subnet assigned to the network. The host must also
have that same subnet in its IP address. Note that connections lines on diagrams are independent logical
TCP/IP based connections to each device (from a PCCU instance for each). The host connects to any
available Ethernet port on any of the XIOs (physical connection not shown).
